SASH- FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 619,444, dated February14, 1899.

Application filed December 19, 1898- Serial No. 699,721. (No model.)

T0 at whom it may concern.-

Be it known that I, JESSE FRANK SMITH, a citizen of the United States,residing at Hattiesburg, in the county of Perry and State ofMississippi, have invented a new and useful Sash-Fastener, of which-thefollowing is a specification.

The invention relates to improvements in sash-fasteners.

The object of the present invention is to improve the construction ofsash-fasteners and to provide a simple, inexpensive, and efficientdevice adapted to be readily applied to any ordinary window and capableof holding a sash at any desired adjustment and of permitting the sameto be readily raised and lowered.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is an elevation of a window provided with asash-fastener constructed in accordance with this invention. Fig. 2 isan enlarged vertical sectional View. Fig. 3 is a detail perspective viewof the casing. Fig. 4 is a similar view of the spring-catch.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 designates a vertical rod having its ends 2 bent inwardly at rightangles and secured to a window-frame, as illustrated in Fig. 1 of theaccompanying drawings, the inturned ends being perforated for thereception of screws. The rod, which extends the entire length of thewindow, is adapted to be engaged by a fastener 3, secured to each of thesashes and consisting of a casing 4 and a spring-catch 5, arrangedwithin the casing and projecting outward therefrom, as clearlyillustrated in Fig. 2 of the accompanying drawings. The casing, which issubstantially rectangular, is provided at its front with openings 6,through which extend the sides of the frame, and the sides of the casingare provided, adjacent to the said openings, with curved notches formingseats or jaws for engaging the rod. The seats or notches 7 cooperatewith the spring-catch in holding a sash at the desired adjustment, andthe casing is provided at its front, between the openings 6, with atongue or piece 8.

The spring-catch which engages the rod is constructed of a single pieceof resilient ma* terial, which is doubled at its center to form an eye9, and the side portions of the mate'- rial are curved outwardly to forma pair of diverging arms 10. The arms 10, which are provided withregistering perforations 11 to receive the rod, are maintained normallyin engagement with the same by the resiliency of the metal, and they arecapable of engaging the rod with sufficient power to support a sash atan elevation. The rod, which extends through the front portion of thecasing, passes inside of the front tongue, and when it is desired toadjust a sash the diverging arms or sides of the springs are compressedand caused to release the rod, and the sash may then move freely.

The casing is secured to its sash by a screw 12, which also passesthrough the eye of the spring-catch, and in order to assist in holdingthe casing firmly in place its sides and.

tongue are provided with spurs. These spurs are embedded in the woodworkof the sash and prevent the same from turning on the screw.

The invention has the following advantages: The sash-fastener, which issimple and inexpensive in construction, is strong and durable andadapted to be readily applied to any ordinary window, and it is capableof holding a sash at any desired adjustment and of permitting the sameto be readily raised and lowered. The screw, which secures the casing tothe window-sash, also serves as a means for connecting the spring andthe casin Changes in the form, proportion, and minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of this invention, such as employing arod for each of the sashes of a window or a single rod extending onlyhalf the length of the same when it is desired to provide but one of thesashes with a fastener.

What is claimed is 1. A device of the class described compris= ing acasing, a substantially V-shaped spring provided at its apex with an eyeand having registering openings at opposite sides thereof to receive arod, and a fastening device passing through the casing and the eye ofthe spring and connecting the said parts and also securing the device toa window, substantially as described.

2. A device of the class described comprising a casing, having openingsat its front and provided between the openings with a tongue and withseats at the outer sides of the openings, a rod passing through thecasing at the inner side of the tongue and arranged in the said seats, asubstantially V-shaped spring provided at its apex with an eye andhaving registering openings at its sides to receive the rod, and afastening device passing through the casing and the eye of the springand adapted to secure the device to a sash, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

JESSE FRANK SMITH.
